Embodiment
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
As shown in Figure 1, this radiator 10 comprises a pedestal 12 and is located at the radiating fin group 16 on this pedestal 12.
Please refer to Fig. 2, this pedestal 12 is roughly rectangular plate-like, and it comprises a smooth lower surface 120 and a upper surface 122 relative with this lower surface 120.This lower surface 120 is for fitting with a heat-generating electronic elements.The relative both sides of this upper surface 122 are respectively provided with a fixed part 121.These two fixed parts 121 be parallel to each other interval arrange, its by extruding or other modes formed.Each fixed part 121 comprises the boss 123 upwards extended by the upper surface 122 of this pedestal 12 and the butting section 125 extended in the direction near the side of another boss 123 to another boss 123 by the top of this boss 123, surrounds a groove 126 between this butting section 125 and upper surface 122 of boss 123 and this pedestal 12.Each boss 123 is upwards vertically extended to form by the upper surface 122 of this pedestal 12, and its cross section is rectangle.Each butting section 125 is by the side of the boss 123 at its place to the direction horizontal-extending of another boss 123, and its upper surface is provided with a groove 128.This groove 128 along this butting section 125 longitudinal extension and run through the relative both sides, front and back of this pedestal 12.
This radiating fin group 16 is arranged by some parallel fin 160 and forms.Please refer to Fig. 3, each fin 160 comprises a body 161, is bent one first flanging 162,1 second flanging 163, two the 3rd flangings 164 and two Fourth Folds 165 of extension by the outer rim of this body 161 in the same way.This body 161 is roughly an inverse-T-shaped structure, it comprise a rectangular plate-like pars intermedia 166 and by this pars intermedia 166 near outward extending two extensions 167 in relative both sides of its bottom position.This two extension 167 is also rectangular flat shape, and the plane at the plane at its place and this body 161 place is in same plane.This first flanging 162 vertically bends extension by the top of this pars intermedia 166 and forms.This second flanging 163 is relative with the first flanging 162, and it vertically bends extension by the bottom of this pars intermedia 166 and two extensions 167 and forms.These two the 3rd flangings 164 vertically bend extension by the top of these two extensions 167 respectively and form.These two Fourth Folds 165 are connected between the 3rd flanging 164 and this second flanging 163 respectively, and it vertically bends extension by the side away from pars intermedia 166 of these two extensions 167 respectively and forms.First flanging 162 of each fin 160 and the second flanging 163 are respectively equipped with the first flanging 162 of the fin 160 be adjacent and the buckle structure 168 of the second flanging 163 cooperation, this radiating fin group 16 is mutually fastened by these buckle structures 168 and is assembled into together, and the extension 167 of each fin 160 after assembling forms a protuberance 169 respectively in the relative both sides of the bottom of this radiating fin group 16.First flanging 162 of each fin 160, second flanging 163, 3rd and Fourth Fold 164, 165 is identical by the outward extending width of this body 161, when these groups of fins install to together, first flanging 162 of one fin 160 of rear assembling, second flanging 163, 3rd and Fourth Fold 164, 165 are resisted against on the body 161 of last fin 160 respectively, thus make these first flangings 162 and the second flanging 163 form a smooth end face and bottom surface respectively at the top of this radiating fin group 16 and bottom, these the 3rd flangings 164 form a loading end 170 in the top of these two protuberances 169, these Fourth Folds 165 form a supporting surface 172 respectively in the side of these two protuberances 169.
Please refer to Fig. 4, one tool 20 is provided, this tool 20 comprise a substrate 21 and by the relative both sides of this substrate 21 to two drifts 22 of downward-extension, each drift 22 is in tabular, its last side is provided with an edge of a knife 221, and this edge of a knife 221 is tiltedly extended internally by the outside of this tool 20.Distance between this two drift 22 slightly larger than the pars intermedia 166 of each fin 160 along the width on its two protuberance 169 line direction.
When assembling this radiator 10, this radiating fin group 16 is slipped into by the side of this pedestal 12 and is installed on the upper surface 122 of this pedestal 12, and these two protuberances 169 are contained in two grooves 126 of this pedestal 12.This tool 20 is located in this radiating fin group 16, and make the edge of a knife 221 of two drifts 22 of this tool 20 aim at groove 128 position of two butting sections 125 of this pedestal 12 respectively and apply pressure downwards simultaneously, these two butting sections 125 are made to suppress the loading end 170 of the protuberance 169 of this radiating fin group 16 downwards, thus firm for this radiating fin group 16 is assembled on this pedestal 12, make simple, and can make can reach tight and firm combination without the need to being coated with scolding tin between the two, thus cost-saving and environmental protection.Because these two butting sections 125 are respectively equipped with groove 128, when tool 20 impacts groove 128 position of these two butting sections 125 downwards and makes butting section 125 be out of shape the protuberance 169 of this radiating fin group 16 of compacting downwards simultaneously, can make this butting section 125 that the upper surface of the boss 123 of this pedestal 12 can not be driven to be out of shape, thus when can prevent from being assembled on an electronic component by this radiator 10 by the installed part be located on this two boss 123, affect its assembling.In addition, the setting of two loading ends 170 of this protuberance 169, and by two butting sections 125 of downward simultaneously this radiator 10 of punching press of tool 20, it can be made to make it stressed evenly, thus strengthen its reliability.Meanwhile, the below of this loading end 170 is respectively equipped with supporting surface 172, and this supporting surface 172 can strengthen the bearing capacity of this loading end 170, thus strengthens this two loading end 170 to the support of this butting section 125, and then combines closely both reaching.Secondly, because two drifts 22 of this tool are all in tabular, therefore, each drift 22 is behind the butting section 125 of this pedestal 12 correspondence of downward punching press, butting section 125 can be made to form linear tight fit with the protuberance 169 of this radiating fin group 16, be conducive to increasing this pedestal 12 and the contact area of radiating fin group 16, improve tightness and the radiating efficiency of the combination of radiator 10.
